When you’re trying to lose weight, fast food is often the first thing to get cut—but experts say it doesn’t have to be completely off-limits. In fact, dietitians note that with the right choices, even a trip to McDonald’s can fit into a balanced, calorie-conscious routine. The key is knowing which menu items offer satisfying protein and portion control—and which ones are loaded with excess calories, fat, and sodium.
From surprisingly solid picks like the Filet-O-Fish and Egg McMuffin to heavier options that can quickly derail your goals, nutrition experts are breaking down the best and worst items to order this spring if you’re aiming to slim down without sacrificing convenience.
The Difference Between Dragging Through Your Day And Feeling Great On Your Feet? These Arch Support Insoles
Best
1. Filet-O-Fish
Dietitian Jenna Hunter says the Filet-O-Fish, which is made of breaded fish fillet, tartar sauce, and a bun, provides a substantial amount of protein, making it a satisfying choice for those looking to increase their protein intake. Fish is naturally rich in protein and contains essential nutrients such as omega-3 fatty acids, which are beneficial for heart health. Despite being a protein-rich option, it's essential to note that the Filet-O-Fish also comes with higher levels of sodium and saturated fat due to its breading and tartar sauce, which is why moderation is key.
Hunter tells us that this option provides 380 calories and 15g protein. "What many people don’t know is that fast food can be a part of a healthy weight loss journey," she assures us. "McDonalds menu item [like this one] can help lead to a healthy weight loss for people who are wanting to control their meal portions, who dislike cooking but still want something that is lower in calories/high in protein, & for people who need something quick."
2. Egg McMuffin
Dietitian and health expert Krutika Nanavati tells us that an egg McMuffin offers a substantial protein boost for breakfast, thanks to the egg and lean ham.
Eggs are renowned for their high-quality protein content, vital for muscle repair and growth, making this sandwich a nutritious option to kickstart the day.
"Starting the day with a high-protein breakfast can kickstart metabolism and reduce the likelihood of overeating later in the day. The protein and whole grain muffin offer sustained energy levels, making it easier to stick to a calorie-restricted diet," she notes.
Nanavati seconds this. "High-protein meals can aid weight loss when part of a balanced diet. Protein promotes muscle maintenance and growth, curbs cravings and snacking, and is more filling than carbs or fats.
Choosing grilled over fried and adding vegetables can lower calorie density for easier weight-loss integration," she says.
Worst
1. Double Quarter Pounder With Cheese
Dr. Erik Natkin thinks the Double Quarter Pounder with Cheese is one of the worst items on the McDonald's menu for quite a few reasons. "This item contains approximately 740 calories, 42 grams of fat (19 grams of which are saturated fat), and 1,360 milligrams of sodium," he notes, and that's probably because these high levels of unhealthy fats and sodium can lead to clogged arteries and increase the risk of heart disease.
Regular consumption of such a heavy, fatty meal can lead to elevated cholesterol levels and hypertension, which are major risk factors for cardiovascular problems.
2. Big Breakfast With Hotcakes
The Big Breakfast with Hotcakes is another particularly unhealthy choice. Dr. Natkin explains that this meal "packs around 1,340 calories, 63 grams of fat (25 grams saturated fat) and 2,070 milligrams of sodium."
The combination of high calories, excessive fats, and salt can elevate bad cholesterol (LDL) levels and raise blood pressure, which are detrimental to heart health. The large quantity of calories in one single meal can also contribute to weight gain, which further increases the risk of heart disease.
